2 Claims:

My invention relates to an improvement in .dye-

Heretofore, it has, beencustomary. to drive the so-called winding-outroll. from theperiphery' of i is to reduce any backlashspeed. of thewinding. roll. can. bermade proper and suitable for thework beingdone,.and-with out any regard for, the speed jof cloth usedqinn dyeing.l

This, invention, therefore, consists in:.an.,at-:

tachment which may be usedonpresent dye jigs of various designs. andwhich will .greatly reduce the time necessary to get the-.clothponto andoff.

: the machine rolls.

One of the primary objects of this invention;

is the time saving element, meaning; the provision of a constructionwhereby the manipulation.

of the cloth can be done in a'small fraction of 30. vthe time hithertorequired.

By actual test, I have provided a machinein:v

which the time of unwinding the cloth from the machine is ,reducedto.about, one-fourth, .at the same time doing a better j0b:;With1.arresultant 351' more uniform winding of the cloth on-the storage rollas it leaves the machine.

As a preliminary to, a fuller description of de-.

tails and operation, it may besstatedthat cloth to be dyed usually comeswrapped around a wood- .en core through which a steel shaft passes sothat the ends protrude beyond the rolls. When the machine-is entirelyfreeof cloth; the wooden core with the roll of dyed cloth is removed:This operation of taking the cloth ofiof the machine generally requiresabout forty five minutes; and i Fig. 1 is a top. plan View brokenoutthrough.

Referring to the drawings: This dye jig consists. essentially of a dyetank or vatl, for containing dye fluid, and in the bottom of the tankorvat-is a suitable drain connection 2. The tank or vat. is generallyenclosed within a suitable structure .orframe A which latter carries therolls and structure above the tank;

Near the bottom of the tankers-two rolls 3, Figs. 2,. 3 and 4, thepurpose of which is to guide the. clothor goods as it: is. passedthrough the dye fluid.:.

Above .the tank .are two rolls 4 and 4, upon whichzzthee cloth isgwoundand unwound as it passes ,;through the dye- On one end, of these rolls!and-A are keyedbevelgears 5 and 5'. Bevel gears Sand 5' meshwithbevelgearsgfi and 6', Fig.:3.., These. gears .6 and 6" have longsleeves IandfI, andarle fitted loosely on the drive shaft 8.1 However,. thesleeves-are fitted withfriction clutches!) .and'B soconstructed that thedriving hUbSL10fthe .clutches are keyedto the shaft'8. Aclutch'ishifterl 0 is provided andmounted tightly on theshifter shaft,.l I. Depending arms I2 are mountedon: shifter shaft II, and engageupstanding-qleversillr Levers l3 are keyedto the. endsmfitwolever.shafts I4,which terminate in the .:.operator,: so that .by, a partial.rotation of either lever handle I5, thexoperator,.moves theclutchg'shifter and thereby engages oneof the clutches..;and at. thesame time disengages the other. By engagingqa clutch, he connects thatclutch andgear tothe drive-shaft 8, and causes the roll.' toyrotate withtheishaft. Likewise, by disengaging the clutch; he disconnects (the,roll from the.drive shaft. This action is necessary, due to the factthat the unwinding roll is revolving-at continually changing revolutionsper minute dueto the different diameters of the cloth due to winding orunwinding on the rolls.

In Fig. 4 the cloth is shown by line I6, winding onto. roll 4 from roll4. Just as the roll 4 gets practically emptyof cloth, if it is desiredto pass handles 15,: located within convenient reach of the cloth backthrough the dye, the operating levers I5 are brought to central position(otherwise neutral) as shown in Figs. 3 and 4, which disengages bothclutches and stops both rolls. The cloth is now passed to the oppositeside of roll 4, as shown by dotted line H, then the operating lever isshifted in the direction of arrow D, which causes the clutch to engageand. start up roll 4 in the direction of arrow B, which continues untilall the cloth is wound on the roll 4. In this Way the cloth can bepassed back and forth through the dye as many times as necessary.

However, suppose the cloth has received sufficient dye and practicallyall the cloth is Wound mechanism, just as the cloth is unwound from roll4, Fig. 4, the rolls are stopped by again shifting operating levers I5to neutral, as shown in Figs. 3 and 4, when the end of the cloth iscarried up over the top roll I8, as shown by dotted line l9. Roll I8 isnow started in the direction of the arrow E by shifting the lever 20,which throws clutch 2! on driving shaft 8 into engagement as shown inFig. 4. Roll I8 continues to run at a constant number of revolutions perminute, until it has received all the cloth in the machine, after whichthe roll with the cloth is removed from the machine.

A desirable feature of my present invention resides in the location,construction, and method of driving this upper roll I3. It will be notedthe roll is placed at a suitable location above and tween rolls 4 and 4.

roll. Suitable means are provided for driving the roll I8 from the driveshaft 8, and claw clutch means 2l25 is provided for disengaging saiddrive from the drive shaft.

The driving means above referred to for roll I8, as shown in dottedlines in Fig. 1, consists of a pair of bevel gears 22 on the shafts 35and36 (see Figs. 1 and 3), with belt and pulleys, or

The clutch "nected with the shifter lever 28 is pull-rod -26,

terminating in an upturned handle 21, on the end of the machine oppositefrom the lever 28 so that the clutch 2| can be operated from either sideof the machine. The members 2| and 25 of the clutch mechanism haveinwardly projecting ratchet teeth, one surface of which teeth slopes inopposite directions in said members, whereby to cause them to push apartwhen the speed of the top roll exceeds the speed of the drive shaft,whereby said roll will finally stop without the at-' tention of theoperator.

From the foregoing description; it will be apparent that roll I8 windsup the cloth thereon with increasing speed the longer it runs, and untilthe completion of the winding and the roll is ready to be 'removed fromthe machine, due. to the fact that the rotary motion is transmitted atthe axial center of the roll instead of at the I means 2I-'25, the rollwould have a tendency to spool or core on the shaft.

travel faster by momentum than the driving mechanism, and therebyautomatically throw the clutch out of gear, so that the roll would cometo a stop automatically.

The driving-head 28, Fig. 1, for roll I8 is shown in detail in Figs. 5,6 and 7, and it will be noticed that there is a square counterbored hole31 about one and one-half inches square, in the end of the head. Anapproved means for supporting the roll I8 is indicated in Fig. 5. Thispreferably consists of a square steel shaft 38 turned round for abearing on one end 39 and left; square on the other end to engage thedriving-head 28 on the shaft 36 through the square hole 31.

The roll I8 is preferably in the form of a hollow wooden spool or core,as shown in Fig. 5. On this spool or core the cloth is wound. Wedgebushings 4| are provided to tighten the Wood This complete spool or corewith or without the cloth Wound thereon, is removable from the machine.

This-attachment is used for placing the cloth in the machine as well asremoving it.

For example: A roll of cloth 30 to be dyed is brought to and placed inthe machine as shown in Figs. 4 and 5, and when raised into properposition, the square end of the shaft 38 is placed in the square hole 31in drive head 28, and the round end 39 is placed in stand-box 29. Theroll will. then .be large, full of cloth, and in the machine as'shownat'38, Figs. 4 and 5. The end of the cloth is then brought down pastroller 4 and on around the two rollers 3 and up to roller 4.

Roller 4 is put inoperation and winds the cloth Suitable bearingsupports are provided for the upon same, see arrow C, Fig. 4.

I have shown in the'foregoing how cloth can be unwound from the machineonto roll I8, as shown by dottedline I9. However, in the event cloth iswound on either of rolls 4 or 4', and it is desired to remove same fromthe rolls without passing ,it through the dye, this can be done bythreading the end of cloth on either of rolls 4 or 4' up' and directlyupon the periphery of roll I8.

An adjustable friction band brake maybe providedas shown at 3|, thisacting as a brake to retard the roll I8 when same is idling andunwinding the cloth onto the machine roller. It will be noted clutch 2|is disengaged and the roll is idling when the cloth is being unwoundtherefrom.

similar friction band brakes may be applied to the ends of rollers 4 and4', as illustrated by numerals 3| (Figs. 1 and 4) for retarding theserolls when they are idling. T

After the cloth has been drawn back and forth through the dye as'manytimes as required, it maybe 'desirable'to rinse out the cloth. This isdone by draining out the dye through the drain 2, whereupon the vat I isfilled and refilled with fresh waterand the cloth is drawn back andforth therethrough until suificiently rinsed, after which it may bethreaded into and wound over the roll I8, as hereinbefore described,completely dyed and ready for removal from the machine.

It is desirable that the rolls 4, 4 and I8 be all located over the vat,and that roll I 8 is preferably located above and in the space betweenrolls 4 and 4 so that drainage from each roll will drop directly intothe vat below.

I claim:

1. The combinationof a frame, a tank having guide rollerstherein,winding rolls journaled on the-frame above the tank, adrive-shaft, gears for transmitting rotary motion from the drive shaftto the said rolls, clutch mechanism on the drive shaft, means forshifting the clutch mechanism to cause motion to be transmitted to oneroll or the other, a storage roll located above the drive shaft andparallel with the first-mentioned rolls, transmission means from thedrive shaft to the axial center of the storage roll characterized by ashaft, gears, a pulley on said shaft and one loose on the drive shaft, abelt extending over said pulleys, the hub of the pulley on thedriveshaft having claw teeth to form a clutch member, a clutch memberkeyed to slide on the drive shaft, and means within the control of theoperator for shifting the clutch member.

2. The combination of a frame, a tank having guide rollers therein,winding rolls journaled on the frame above the tank, a drive-shaft,gears for transmitting rotary motion from the drive shaft to the saidrolls, clutch mechanism on the drive shaft, means for shifting theclutch mechanism to cause motion to be transmitted to one roll or theother, a storage roll located above the drive shaft and parallel withthe first-mentioned rolls, transmission means from the drive shaft tothe axial center of the storage roll characterized by a shaft, gears, apulley on said shaft and one loose on the drive shaft, a belt extendingover said pulleys, the hub of the pulley on the drive-shaft having clawteeth to form a clutch member, a clutch member keyed to slide on thedrive shaft, the members of said clutch mechanism having inwardlyprojecting claw-teeth, one surface of which teeth slopes in a directionwhich will cause them to push apart when the speed of the top roll dueto its momentum exceeds the speed of the drive-shaft, whereby said rollwill stop automatically without the attention of the operator, and meanswithin the control of the operator for shifting the clutch member.
